There could also be new characters created specifically for this fanfic. For example, a powerful red - alien leader who is very protective of his territory and a blue - alien strategist who is always looking for ways to gain an advantage. These new characters could add more depth and conflict to the story.
Ben Tennyson would probably be a main character, whether in his normal form or transformed into different aliens. He could be on either the red or blue side depending on the story's take.
Gwen Tennyson might also be involved. She could play a mediator role between the red and blue factions, using her magic powers. And maybe Kevin Levin, who could side with one of the groups based on his own interests or past relationships with the characters.
Some of the main characters include Church, Tucker, and Caboose. Church is often a central figure, known for his sarcastic and sometimes mysterious nature. Tucker is the one with the sword and has his own set of comical adventures. Caboose is the big - hearted but not - so - bright character who often gets into trouble and provides a lot of the humor.
Yang and Tucker could also work well together. Yang is strong and confident, while Tucker has his own brand of bravado. They could get into all sorts of adventures and battles, with Yang using her brawler style and Tucker with his sword and unique abilities. Maybe they'd compete for who can take down the most enemies in a fight.
In this 'caboose's wedding red vs blue fanfic', Caboose is the central character for obvious reasons. Then, considering the nature of Red vs Blue, characters like Tex might also be involved.

They might be responsible for security during the wedding or for making sure everything goes according to plan in their own bumbling ways.
One idea could be a battle between the red - themed and blue - themed aliens from Ben 10 in a unique setting. Maybe they are fighting over a powerful artifact.

The 'Red vs Blue' full story has a cast of main characters that are integral to the narrative. Church is a prominent character, especially known for his sarcastic and sometimes cynical nature. His relationship with the other characters, especially Caboose, is a major part of the story. Tucker, with his self - proclaimed charm and his special weapon, adds a lot of comical and action - oriented elements. Simmons, from the Reds, provides a contrast with his more serious and rule - following attitude. Caboose, on the other hand, is perhaps the most endearing character. His lack of understanding and his child - like innocence often lead to hilarious situations and also help in bringing out the different sides of the other characters as they interact with him.
Ben himself would definitely be the main character as it's about him being sick. His Grandpa Max is likely to be there, as he is always looking out for Ben. Gwen, his cousin, would also probably be in it, trying to use her magic to help Ben get better or at least understand what's wrong with him.
Sasuke and Tex might be likely to be paired up. Both are strong and somewhat brooding characters. Sasuke's quest for power could be paralleled with Tex's own abilities and her role in the Red vs Blue universe. They might engage in some intense battles or even end up having to work together against a common enemy, leading to some interesting character development for both of them.

Similarly, a charming and intelligent leader of the blue group could also be well - liked. Additionally, any character with unique abilities or a tragic backstory within the harem can gain popularity among readers.
One likely narrator could be one of Epsilon's closest comrades.
